Patent CA-2038700-A1 (CA)
IPC: B29C31/00
Filed: 1991-03-20
Abstract: Abstract of the Disclosure An apparatus engages pre-cut lengths of heated thermoplastic pipe against a pair of eccentric wiper arms bending the pipes into elbows.  The eccentric wiper arms have an eccentric portion and a constant radius portion.  A bending form has an arcuate die adapted to hold a pre-cut length of pipe.  Four such bending forms are radially connected to a rotation shaft which is journalled at each end to a support frame.  A continuous supply of pre-cut lengths of pipe are transported through a heating chamber by a set of endless chains.  Each pipe is then transferred to a bending form which is rotated by the shaft so that the cold end portions of each pipe engages the spaced apart and substantially parallel eccentric wiper arms.  The wiper arms urge the end portions of each pipe length slightly beyond the outer edges of each arcuate die to compensate for the effect cooling has on each pipe length.  Once the pipe is bent, the rotation of the bending form causes the pipe to drop into a tank of water.  A pump circulates cooled water through the tank so the water is maintained at approximately 40° Fahrenheit.  When water is pumped into the tank enough water flow is created to urge the elbows toward a conveyor belt.  Another pump creates water flow that urges the elbows onto the conveyor belt which removes the elbows from the tank and drops them in a storage bin.

Patent CA-2046851-A1 (CA)
Inventor: STORM JOHN M
IPC: H05B6/06
Filed: 1991-07-11
Abstract: An induction hardening machine for contour hardening of machine components such as gears includes a phase angle detector circuit (112) which produces a pulse for each corresponding detection of a predetermined phase angle of an AC signal. A start switch (SW2) and the pulse produced by the phase detector provide inputs to a circuit (116) which requires concurrence of the pulse and activation of the switch before a predetermined width signal pulse is produced. The predetermined width signal pulse activates power switching devices (114) to supply a predetermined power signal to an RF generator (120) coupled to an induction heating coil (128). Precise induction heating is accomplished via precise control of power input to the RF generator (120).

Patent CA-2052812-A1 (CA)
Inventor: LINDLEY DANIEL D
IPC: C07C51/60
Filed: 1991-10-04
Abstract: A continuous process is disclosed for the acylation or alkylation of aromatic compounds in hydrogen fluoride. The aromatic compound is sufficiently insoluble in hydrogen fluoride that a two phase reaction medium forms. However, surprisingly, the product acylated or alkylated aromatic compound is soluble in hydrogen fluoride. The present invention particularly relates to use of a continuous, multi-stage process for carrying out the acylation or alkylation reaction. In the multi-stage process, the continuous phase can be either the hydrogen-fluoride rich phase or the aromatic compound-rich phase. The movement of the continuous phase relative to the non-continuous (dispersed) phase can be countercurrent or concurrent. The multi-stage process can be operated in a manner such that the aromatic compound feed to the reaction is entirely consumed or such that unreacted aromatic compound is recycled.

Title: Composite intraocular lens and method of manufacture
Inventor: VANDERBILT DAVID P
IPC: A61L27/16
Filed: 1991-12-23
Abstract: The new intraocular lens of the present invention is a one-piece composite lens having a soft, foldable central optic region and a hard, non-foldable outer peripheral region making up the haptics or legs of the intraocular lens. The soft, central optic portion of the lens is typically manufactured from a material capable of being folded so that the intraocular lens can be inserted through a small incision on the order of 3 to 4 mm. The hard haptic portion of the lens provides support for the lens in the eye after insertion and unfolding of the lens. The relatively rigid plastic lends support to the entire lens structure after its insertion into the posterior chamber of the eye, and tends to help stabilize the position of the lens after insertion and the closure of the incision. A preferred material of the soft optical region being a poly(hydroxyethyl methacrylate) or pHEMA or a copolymer thereof such as HEMA and 6-hydroxyhexyl methacrylate (HOHEXMA) or p(HEMA-co-HOHEXMA). The preferred material of the hard haptic region being made from a relatively hard plastic, such as (polymethyl methacrylate) or PMMA, or a copolymer thereof.

Title: Self-emulsifying glasses
Inventor: SHIVELY MERRICK L
IPC: A61K9/107
Filed: 1991-05-31
Abstract: The present invention provides compositions and method for the preparation of emulsions and multiple emulsions. Specifically, the invention provides solids which are self-emulsifying glasses which, on contact with a sufficient amount of an aqueous phase, form emulsions or multiple emulsions without input of emulsive mixing.  Emulsions and multiple emulsions produced from the self-emulsifying glasses are encompassed by this invention. The self-emulsifying glasses are prepared from certain matrix compounds and an oleaginous material by a solvent method. The glass results from removal of solvent from a combination of matrix compound, oleaginous material and a solvent which dissolves substantially all of the matrix compound. Multiple emulsions result from glasses in which the oleaginous phase is a primary, e.g. water-in-oil emulsion. The glasses and emulsions produced therefrom are particularly useful pharmaceutical, food and cosmetic applications.

Abstract: A PASSIVE THREE-PHASE HEAT TUBE FOR THE  PROTECTION OF APPARATUS FROM EXCEEDING MAXIMUM OR MINIMUM SAFE WORKING TEMPERATURES     ABSTRACT OF THE DISCLOSURE Safety equipment is disclosed comprising a three-phase heat pipe for the protection of apparatus from exceeding maximum or minimum safe working temperatures.  The heat pipe has a working fluid selected so that it will not function below the desired temperature.  A working fluid which has a melting point slightly above the minimum safe temperature of the equipment to be protected is preferred for protecting equipment from exceeding it minimum safe working temperature.  This heat pipe may be used to cool an apparatus to a temperature where the heat pipe automatically stops functioning and keeps an apparatus from exceeding its minimum design temperature. working fluid which has a melting point slightly below the maximum safe temperature is preferred to keep equipment from exceeding its maximum safe working temperature.  This heat pipe will be inactive at normal operating temperatures but will release excess heat to cooler surroundings before safe working temperatures are exceeded. Transfer may also be by capillary action in a heat pipe having a wick.
